Normally I wouldn't, but the need to diag overrides that. If I need to replace the hose afterwards, fine. But I wanted to narrow down the problem, if possible.
I can't answer any of those for certain tonight, but good things to check for. I might pull the calipers tomorrow and check that they extend and don't retract on their own. The caliper pins don't go into a blind hole, so that's probably not an issue. But checking freedom of movement on the pins themselves is another good one to check.
Yes, bleeders are up, I removed them, used a block to simulate the rotor and tried rolling them around while using the vacuum bleeder. Nothing,.
